He's not the same
Laura Allen was the engineer and architect for the Prometheus, along with David 8. Laura had spent many nights designing and building the Prometheus with him. But when the time came she decided not to go on the voyage. They all disappeared and so did David. Not any sign of them for ten years as the last message they sent said not to try and find them. Now Laura, wanting to forget the past, has boarded the Covenant, the only crew member without a partner. But with a new life on Origae-6 waiting, and a strange new signal coming out how can she forget the past?
